We encountered this error while running multithreaded performance tests on our application, which uses Javers for versioning of database changes. See below for full stack trace.

I think this looks like an error inside or while accessing the polyjdbc class Sequence without proper synchronisation for thread safety, so this may be a bug inside polyjdbc. Therefore I've created an issue for polyjdbc, too: polyjdbc/polyjdbc#22

Do you think this assumption for the cause of the exception is correct?

Suggestions for fixing this in Javers:

  • either update polyjdbc when this issue is fixed in polyjdbc
  • or implement a workaround to ensure thread safety in this case.

Thanks for reporting, we will check it.
Could you push the reproduction scenario (a failing test)?
